TM 5-3805-262-101-16. BRAKESPARKING BRAKE VALVE. Controls flow of air to actuator. Pushing knob in applies airpressure to actuator in turn releasing parking brake. Pulling knob out releases airpressure applied to actuator. Large spring in actuator then moves piston causinglinkage and lever in parking brake to force brake shoes against brake drum.ACTUATOR. Located left side of loader. Includes large spring and piston. When airpressure applied by parking brake valve, it pushes against piston and compressesspring in turn releasing parking brake. When air pressure released, large springforces piston to move and apply parking brake.PARKING BRAKE. Mounted on transmission output shaft. Drum type parking brake pre-vents axles and wheels from rotating when applied.BRAKE TREADLE VALVE. Depressing treadle valve applies air pressure to brake actua-tors. This in turn applies hydraulic pressure to brake calipers mounted on eachwheel end and applying brake pads to disks mounted on wheel ends to stop loader.Brake actuators consist of an air chamber and hydraulic master cylinder. Also turnson stop or black out stop lights as determined by position of vehicle lights switch.Brake system is air over hydraulic.SERVICE BRAKES. Disk brakes mounted on each wheel end.AIR RESERVOIR. Mounted at right side of loader. Air from air compressor routed toand stored in air reservoir until required by air system components.1-18
